LIQUID COOLED LASER BAR ARRAYS INCORPORATING THERMAL EXPANSION MATCHED MATERIALS

摘要

A laser diode array having a plurality of diode bars (16) sandwiched between thermal expansion matched spacers (14). The array is mounted on a heatsink 30 with intervening ceramic layer 28 using a hard solder (16). The spacers are formed of an aluminum/diamond composite, a silver/diamond composite or a silver/aluminum alloy/diamond composite material having a thermal expansion that closely matches that of the laser bars.
